Class ByteArraySerializer

java.lang.Object
edu.internet2.middleware.grouperClientExt.com.fasterxml.jackson.databind.JsonSerializer<T>
edu.internet2.middleware.grouperClientExt.com.fasterxml.jackson.databind.ser.std.StdSerializer<byte[]>
edu.internet2.middleware.grouperClientExt.com.fasterxml.jackson.databind.ser.std.ByteArraySerializer
All Implemented Interfaces:
JsonFormatVisitable, SchemaAware, Serializable
public class ByteArraySerializer extends StdSerializer<byte[]>
Unlike other integral number array serializers, we do not just print out byte values as numbers. Instead, we assume that it would make more sense to output content as base64 encoded bytes (using default base64 encoding).

NOTE: since it is NOT serialized as an array, cannot use AsArraySerializer as base

NOTE: since 2.6, has been a main-level class; earlier was embedded in StdArraySerializers.

    • isEmpty

      public boolean isEmpty(SerializerProvider prov, byte[] value)
      Description copied from class: JsonSerializer
      Method called to check whether given serializable value is considered "empty" value (for purposes of suppressing serialization of empty values).

      Default implementation will consider only null values to be empty.

      NOTE: replaces JsonSerializer.isEmpty(Object), which was deprecated in 2.5

      Overrides:
      isEmpty in class JsonSerializer<byte[]>

    • serialize

      public void serialize(byte[] value, JsonGenerator g, SerializerProvider provider) throws IOException
      Description copied from class: JsonSerializer
      Method that can be called to ask implementation to serialize values of type this serializer handles.
      Specified by:
      serialize in class StdSerializer<byte[]>
      Parameters:
      value - Value to serialize; can not be null.
      g - Generator used to output resulting Json content
      provider - Provider that can be used to get serializers for serializing Objects value contains, if any.
      Throws:
      IOException

    • serializeWithType

      public void serializeWithType(byte[] value, JsonGenerator g, SerializerProvider provider, TypeSerializer typeSer) throws IOException
      Description copied from class: JsonSerializer
      Method that can be called to ask implementation to serialize values of type this serializer handles, using specified type serializer for embedding necessary type information.

      Default implementation will throw UnsupportedOperationException to indicate that proper type handling needs to be implemented.

      For simple datatypes written as a single scalar value (JSON String, Number, Boolean), implementation would look like: 

        // note: method to call depends on whether this type is serialized as JSON scalar, object or Array!
  typeSer.writeTypePrefixForScalar(value, gen);
  serialize(value, gen, provider);
  typeSer.writeTypeSuffixForScalar(value, gen);
      and implementations for type serialized as JSON Arrays or Objects would differ slightly, as START-ARRAY/END-ARRAY and START-OBJECT/END-OBJECT pairs need to be properly handled with respect to serializing of contents.
      Overrides:
      serializeWithType in class JsonSerializer<byte[]>
      Parameters:
      value - Value to serialize; can not be null.
      g - Generator used to output resulting Json content
      provider - Provider that can be used to get serializers for serializing Objects value contains, if any.
      typeSer - Type serializer to use for including type information
      Throws:
      IOException

    • getSchema

      public JsonNode getSchema(SerializerProvider provider, Type typeHint)
      Description copied from class: StdSerializer
      Default implementation simply claims type is "string"; usually overriden by custom serializers.
      Specified by:
      getSchema in interface SchemaAware
      Overrides:
      getSchema in class StdSerializer<byte[]>
      Parameters:
      provider - The serializer provider.
      typeHint - A hint about the type.
      Returns:
      Json-schema for this serializer.

    • acceptJsonFormatVisitor

      public void acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor, JavaType typeHint) throws JsonMappingException
      Description copied from class: StdSerializer
      Default implementation specifies no format. This behavior is usually overriden by custom serializers.
      Specified by:
      acceptJsonFormatVisitor in interface JsonFormatVisitable
      Overrides:
      acceptJsonFormatVisitor in class StdSerializer<byte[]>
      typeHint - Type of element (entity like property) being visited
      Throws:
      JsonMappingException
